What it does

Codex Debugging is an agent skill from steipete/agent-scripts. Codex debugging: codex-rs core/tui/exec/cli/app-server/config.

Its SKILL.md is about 270 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Debugging. The repository describes itself as: Scripts for agents, shared between my repositories. The licence is MIT.

When your agent uses it

  • Tasks that involve Debugging

Example prompts

  • “/codex-debugging”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Identify whether the behavior is CLI, TUI, app server, protocol, config, or exec/tooling.
  2. Read the owning module and adjacent tests before proposing changes.
  3. Check local config in ~/.codex/config.toml only after understanding the source contract.
  4. Prefer small repros or focused tests over broad speculation.

What it can do on your machine

Read from SKILL.md and the folder at commit 79150cf. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • rg

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Codex Debugging loads about 265 tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 106 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~20
When it runs · the whole SKILL.md, loaded when a task matches
~265

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Codex debugging: codex-rs core/tui/exec/cli/app-server/config.

Codex Debugging

Use when investigating Codex CLI/app behavior, config parsing, tool behavior, prompts, MCP/app wiring, or runtime bugs.

Source First

Prefer local source before web/docs:

bash
cd ~/Projects/codex
sed -n '1,220p' codex-rs/AGENTS.md

Then search targeted areas:

bash
rg "<symbol|setting|error|feature>" codex-rs/{core,tui,exec,cli,app-server,app-server-protocol,config}

Workflow

  1. Identify whether the behavior is CLI, TUI, app server, protocol, config, or exec/tooling.
  2. Read the owning module and adjacent tests before proposing changes.
  3. Check local config in ~/.codex/config.toml only after understanding the source contract.
  4. Prefer small repros or focused tests over broad speculation.

Notes

  • For OpenAI API/product docs, use the official-docs path only when source is insufficient.
  • For local browser automation in CLI, use $browser-use; the bundled Browser plugin is Codex app-only.
